SpaceX looks to launch space tourists to record heights – Teslarati

Published

SpaceX has signed an agreement with a space tourism company that could see its Crew Dragon spacecraft take space tourists to heights unmatched by astronauts in half a century.

On Tuesday, February 18th, Space Adventures announced the agreement, revealing that it is now officially looking for wealthy private customers interested in launching to orbit on a SpaceX rocket and spacecraft. Known as Crew Dragon, that spacecraft is perhaps just two or three months away from SpaceX’s inaugural astronaut launch, in which two NASA astronauts will be sent into orbit to rendezvous and dock with the International Space Station (ISS) before returning to Earth after several weeks or months in space.

Founded in 1998, while Space Adventures has a slightly checkered past and has been more or less inactive for more than a decade, the company did manage to arrange eight separate spaceflights for seven private customers between 2001 and 2009. All flights previously arranged were done so through Russian space agency Roscosmos with Soyuz rockets and spacecraft and involved approximately week-long visits to the International Space Station (ISS), where the private astronauts – all multimillionaires and billionaires – mainly observed routine ISS operations and assisted with science experiments. With SpaceX’s Falcon 9 and Crew Dragon, Space Adventures hopes to soon offer orbital tourists an option that keeps all operations in the United States.

As noted, it must be stated that the February 18th agreement doesn’t actually mean that private customers will definitively launch into orbit in SpaceX’s Crew Dragon spacecraft. Instead, it serves as a semi-contractual confirmation that the spaceflight company is officially willing and ready to support such a mission in the event that Space Adventures is able to secure enough customers to purchase the necessary launch services. While not out of the question, that will be no easy feat.

Thankfully, several aspects of this new agreement should work in SpaceX and Space Adventures’ favor. As a unique ‘free-flying’ mission, Crew Dragon and its space tourists would not actually rendezvous with the ISS – instead serving as its own miniature outpost in Low Earth Orbit (LEO) for several days. Relative to SA’s past tourist flights to the ISS, this will save a large portion of the time and cost associated with both training civilians for spaceflight and ISS operations and working with NASA and Roscosmos to arrange the complex mission.

Aside from simplifying the training and bureaucracy involved in orbital tourism, the fact that Space Adventures’ newest proposal will have no affiliation or involvement with NASA or Roscosmos also means that there’s nothing preventing SpaceX from using a flight-proven Falcon 9 booster and Crew Dragon capsule on its space tourist launch. By combining flight-proven hardware with a space station-free mission profile, SpaceX could theoretically cut the overall flight’s cost by tens or even hundreds of millions of dollars.

According to public analyses performed over the last few years by auditors and researchers, SpaceX Crew Dragon launches will likely cost NASA around $400 million each, while a comparable Boeing Starliner mission will cost the space agency at least $650 million. The SpaceX figure is, however, predicated upon the production of a brand new Falcon 9 rocket and Crew Dragon spacecraft for each launch and includes costs associated with any processing or operations involving NASA teams and facilities.

As noted above, the use of a thoroughly flight-proven Falcon 9 booster and Crew Dragon capsule could dramatically cut the cost of private astronaut launches relative to the NASA baseline. It’s conceivable that – having effectively amortized the cost of the spacecraft and booster with a NASA astronaut launch – such a private mission’s price could be little more than the cost of building a new Falcon upper stage and Crew Dragon trunk, as well as booster/capsule refurbishment and general operations. Conservatively, the ultimate price SpaceX offers or offered Space Adventures could thus be as low as $100-200 million per launch.

Space Adventures says it could support as many as four space tourists on one flight, translating to a cost of $25-50 million per person if all seats are filled. This would compare reasonably well with the $20-50 million it typically charged its seven orbital tourism customers. That is still a vast sum of money and cuts the pool of potential customers to perhaps a few tens of thousands of people worldwide. Nevertheless, Google co-founder Sergey Brin (and possibly others) is on a sort of waiting list (requiring a $5 million deposit) for future orbital Space Adventures flights, giving the company at least one strong prospective customer.

At that altitude, Crew Dragon passengers would be able to glimpse almost 12 times more of the Earth’s surface compared to astronauts on the ISS. In other words, the resulting ‘overview effect’ could be a full magnitude more impressive. (NASA)

Thanks to skipping a space station rendezvous, perhaps the single biggest selling point of the mission is that Falcon 9 and Crew Dragon could potentially send space tourists higher than ever before – to an altitude only certain NASA Apollo and Gemini astronauts can claim to have surpassed. Space Adventures specifically notes this on its website, stating that prospective space tourists could reach an altitude that only Gemini 11 astronauts have surpassed while remaining in Earth orbit.

Gemini 11 astronauts reached an of apogee around 850 miles (1350 km) while still in Earth orbit – a record that stands today. Neither Space Adventures or SpaceX have specifically stated how high an unmodified Falcon 9 and Crew Dragon to launch private astronauts, but the implication is that the view would be comparable to – or even better than – what the Gemini 11 crew saw back in 1966. Regardless, it’s safe to say that if SpaceX and Space Adventures’ new space tourism effort is greeted with healthy demand, we’ll be shortly entering a new era of private spaceflight. Crew Dragon’s first private astronaut mission is tentatively scheduled to launch as early as late-2021 or early-2022.

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.

This report by The Canadian Press was first published Sept. 9, 2024.

Asteroid Apophis will visit Earth in 2029, and this European satellite will be along for the ride

Published

 on

The European Space Agency is fast-tracking a new mission called Ramses, which will fly to near-Earth asteroid 99942 Apophis and join the space rock in 2029 when it comes very close to our planet — closer even than the region where geosynchronous satellites sit.

Ramses is short for Rapid Apophis Mission for Space Safety and, as its name suggests, is the next phase in humanity’s efforts to learn more about near-Earth asteroids (NEOs) and how we might deflect them should one ever be discovered on a collision course with planet Earth.

In order to launch in time to rendezvous with Apophis in February 2029, scientists at the European Space Agency have been given permission to start planning Ramses even before the multinational space agency officially adopts the mission. The sanctioning and appropriation of funding for the Ramses mission will hopefully take place at ESA’s Ministerial Council meeting (involving representatives from each of ESA’s member states) in November of 2025. To arrive at Apophis in February 2029, launch would have to take place in April 2028, the agency says.

This is a big deal because large asteroids don’t come this close to Earth very often. It is thus scientifically precious that, on April 13, 2029, Apophis will pass within 19,794 miles (31,860 kilometers) of Earth. For comparison, geosynchronous orbit is 22,236 miles (35,786 km) above Earth’s surface. Such close fly-bys by asteroids hundreds of meters across (Apophis is about 1,230 feet, or 375 meters, across) only occur on average once every 5,000 to 10,000 years. Miss this one, and we’ve got a long time to wait for the next.

When Apophis was discovered in 2004, it was for a short time the most dangerous asteroid known, being classified as having the potential to impact with Earth possibly in 2029, 2036, or 2068. Should an asteroid of its size strike Earth, it could gouge out a crater several kilometers across and devastate a country with shock waves, flash heating and earth tremors. If it crashed down in the ocean, it could send a towering tsunami to devastate coastlines in multiple countries.

Over time, as our knowledge of Apophis’ orbit became more refined, however, the risk of impact  greatly went down. Radar observations of the asteroid in March of 2021 reduced the uncertainty in Apophis’ orbit from hundreds of kilometers to just a few kilometers, finally removing any lingering worries about an impact — at least for the next 100 years. (Beyond 100 years, asteroid orbits can become too unpredictable to plot with any accuracy, but there’s currently no suggestion that an impact will occur after 100 years.) So, Earth is expected to be perfectly safe in 2029 when Apophis comes through. Still, scientists want to see how Apophis responds by coming so close to Earth and entering our planet’s gravitational field.

“There is still so much we have yet to learn about asteroids but, until now, we have had to travel deep into the solar system to study them and perform experiments ourselves to interact with their surface,” said Patrick Michel, who is the Director of Research at CNRS at Observatoire de la Côte d’Azur in Nice, France, in a statement. “Nature is bringing one to us and conducting the experiment itself. All we need to do is watch as Apophis is stretched and squeezed by strong tidal forces that may trigger landslides and other disturbances and reveal new material from beneath the surface.”

By arriving at Apophis before the asteroid’s close encounter with Earth, and sticking with it throughout the flyby and beyond, Ramses will be in prime position to conduct before-and-after surveys to see how Apophis reacts to Earth. By looking for disturbances Earth’s gravitational tidal forces trigger on the asteroid’s surface, Ramses will be able to learn about Apophis’ internal structure, density, porosity and composition, all of which are characteristics that we would need to first understand before considering how best to deflect a similar asteroid were one ever found to be on a collision course with our world.

Besides assisting in protecting Earth, learning about Apophis will give scientists further insights into how similar asteroids formed in the early solar system, and, in the process, how  planets (including Earth) formed out of the same material.

One way we already know Earth will affect Apophis is by changing its orbit. Currently, Apophis is categorized as an Aten-type asteroid, which is what we call the class of near-Earth objects that have a shorter orbit around the sun than Earth does. Apophis currently gets as far as 0.92 astronomical units (137.6 million km, or 85.5 million miles) from the sun. However, our planet will give Apophis a gravitational nudge that will enlarge its orbit to 1.1 astronomical units (164.6 million km, or 102 million miles), such that its orbital period becomes longer than Earth’s.

It will then be classed as an Apollo-type asteroid.

Ramses won’t be alone in tracking Apophis. NASA has repurposed their OSIRIS-REx mission, which returned a sample from another near-Earth asteroid, 101955 Bennu, in 2023. However, the spacecraft, renamed OSIRIS-APEX (Apophis Explorer), won’t arrive at the asteroid until April 23, 2029, ten days after the close encounter with Earth. OSIRIS-APEX will initially perform a flyby of Apophis at a distance of about 2,500 miles (4,000 km) from the object, then return in June that year to settle into orbit around Apophis for an 18-month mission.

Furthermore, the European Space Agency still plans on launching its Hera spacecraft in October 2024 to follow-up on the DART mission to the double asteroid Didymos and Dimorphos. DART impacted the latter in a test of kinetic impactor capabilities for potentially changing a hazardous asteroid’s orbit around our planet. Hera will survey the binary asteroid system and observe the crater made by DART’s sacrifice to gain a better understanding of Dimorphos’ structure and composition post-impact, so that we can place the results in context.

The more near-Earth asteroids like Dimorphos and Apophis that we study, the greater that context becomes. Perhaps, one day, the understanding that we have gained from these missions will indeed save our planet.
