How to watch NASA astronauts return to Earth on the SpaceX Crew Dragon – Digital Trends

Published

 on


On Saturday, August 1, NASA and SpaceX plan to complete their historic Demo-2 mission, the first crewed test flight of the new Crew Dragon capsule which will ferry astronauts between Earth and the International Space Station (ISS). The spacecraft will undock from the station where it has been since its arrival on May 31 and travel back to Earth with NASA astronauts Bob Behnken and Doug Hurley aboard.

We’ve got all the details on what to expect from the return flight and how to watch the event live online.

The Crew Dragon mission so far

At the end of May, the Crew Dragon capsule with astronauts Behnken and Hurley aboard was launched atop a Falcon 9 rocket from the Kennedy Space Center in Florida. After a smooth and uneventful 19-hour journey, the astronauts arrived safely at the International Space Station with the capsule in good condition.

The astronauts then spent three months on board the ISS, where they assisted the crew with science operations as well as checking on the health of the Crew Dragon. Now NASA and SpaceX are both satisfied that the Crew Dragon capsule has performed as required as has not experienced any issues during launch or while being docked, they are ready for the return leg of the journey to complete this test flight mission.

On the day of the return flight, Saturday, August 1, Behnken and Hurley will say farewell to their ISS colleagues and proceed from the space station back into the Crew Dragon capsule. The capsule will then carefully undock from the station and maneuver to a safe distance.

The capsule will execute four engine burns to point back toward Earth and begin the return journey. This journey takes between six and 30 hours, depending on exactly when departure occurs. This large difference is due to the fact the ISS moves around the Earth so its position relative to the landing zone varies throughout the day.

Once the capsule is approaching Earth’s atmosphere, it will jettison its trunk, or the cylinder in which it sits, which will then burn up in the atmosphere. The small capsule will continue on and enter Earth’s atmosphere traveling at around 17,500 miles per hour, at which speeds friction will cause it to experience temperatures of up to 3,500 degrees Fahrenheit.

Once it is moving through the atmosphere, the capsule will deploy two sets of parachutes to slow its descent before it lands in the ocean. The first set deploys at an altitude of 18,000 feet and the second set at 6,000 feet, slowing the Crew Dragon from 350 mph to 119 mph to a safe landing speed.

The capsule will splashdown in the Atlantic Ocean off the coast of Florida. There are seven potential splashdown sites, including those near to Pensacola, Tampa, Tallahassee, Panama City, Cape Canaveral, Daytona, and Jacksonville. Which location will be used depends on exactly when the craft leaves the ISS and on the weather conditions at each location.

The crew members will then be retrieved by a team of SpaceX and NASA personnel using one of two recovery ships, the Go Searcher and the Go Navigator. They’ll be taken for a medical assessment to check they’re fit and well, then they’ll travel back to dry land where they’ll board a plane which will fly them to Ellington Field base in Houston.

NASA TV will be showing full coverage of the return flight, including a farewell ceremony from the ISS for the astronauts, the undocking of the craft from the space station, and the splashdown in the Atlantic Ocean. There will also be a post-splashdown news conference with NASA and SpaceX representatives to talk about how the return flight went, and after a couple of days of recovery time the astronauts traveling in the Crew Dragon, Behnken and Hurley, will talk about their experiences in a news conference.

On flight day, Saturday, August 1, coverage of the farewell ceremony begins at 6:10 a.m. PT/9:10 a.m. ET., followed by coverage of the undocking beginning at 2:15 p.m. PT/5:15 p.m. ET, with the actual undocking scheduled for 4:34 p.m. PT/7:34 p.m. ET.

The craft will travel back to Earth over Saturday night and Sunday morning, with splashdown scheduled for 11:42 p.m. PT/2:42 p.m. ET on Sunday, August 2. This will be followed by the post-splashdown news conference at 2 p.m. PT/5 p.m. ET.

You can watch all of these events via NASA TV, either by using the embedded video at the top of this page or by heading to NASA’s live TV page.

NASA hears from Voyager 1, the most distant spacecraft from Earth, after months of quiet

Published

 on

 

CAPE CANAVERAL, Fla. (AP) – NASA has finally heard back from Voyager 1 again in a way that makes sense.

The most distant spacecraft from Earth stopped sending back understandable data last November. Flight controllers traced the blank communication to a bad computer chip and rearranged the spacecraft’s coding to work around the trouble.

NASA’s Jet Propulsion Laboratory in Southern California declared success after receiving good engineering updates late last week. The team is still working to restore transmission of the science data.

It takes 22 1/2 hours to send a signal to Voyager 1, more than 15 billion miles (24 billion kilometers) away in interstellar space. The signal travel time is double that for a round trip.

Contact was never lost, rather it was like making a phone call where you can’t hear the person on the other end, a JPL spokeswoman said Tuesday.

Launched in 1977 to study Jupiter and Saturn, Voyager 1 has been exploring interstellar space – the space between star systems – since 2012. Its twin, Voyager 2, is 12.6 billion miles (20 billion kilometers) away and still working fine.

SpaceX launches 23 Starlink satellites from Florida (photos)

Published

 on

SpaceX sent yet another batch of its Starlink internet satellites skyward today (April 23).

A Falcon 9 rocket topped with 23 Starlink spacecraft lifted off from Florida’s Cape Canaveral Space Force Station today at 6:17 p.m. EDT (2217 GMT).

The Falcon 9’s first stage came back to Earth for a vertical landing about 8.5 minutes after launch as planned. It touched down on the SpaceX droneship Just Read the Instructions, which was stationed in the Atlantic Ocean.

It was the ninth launch and landing for this particular booster, according to a SpaceX mission description. Five of its previous eight liftoffs were Starlink missions.

The Falcon 9’s upper stage will continue carrying the 23 Starlink satellites toward low Earth orbit (LEO) today, deploying them about 65 minutes after liftoff.

This evening’s launch was the 41st of the year for SpaceX, and the 28th of 2024 dedicated to building out the huge and ever-growing Starlink megaconstellation. There are nearly 5,800 operational Starlink satellites in LEO at the moment, according to astrophysicist and satellite tracker Jonathan McDowell.

The Starlink launch ended up being the first half of a spaceflight doubleheader: A Rocket Lab Electron vehicle launched two satellites, including a NASA solar-sailing technology demonstrator, from New Zealand today at 6:33 p.m. EDT (2233 GMT).

Editor’s note: This story was updated at 6:30 p.m. ET on April 23 with news of successful launch and first-stage landing.

Getting to know Samantha Letourneau

By day, Samantha Letourneau is Vancouver Island University’s Canada Learning Bond project lead and Volunteer Tutor Coordinator. She’s also a musician and dancer and for the past two years, she’s been collaborating with Swedish artist Mårten Spångberg, thanks to funding obtained through Crimson Coast Dance, to create a digital art installation that goes live on Friday, April 26. A launch event takes place at Black Rabbit restaurant in the Old City Quarter that night. Samantha is also hosting a creative process workshop on April 27 and 28.

Can you share a bit about your background as an artist and how you got into it?

I have been working in art for a very long time, as a musician and dancer as well as an art administrator and program coordinator. I started music at the age of 11 and dance came later in my life in my early 20s. I always wanted to do dance, but I grew up in a small community in Yellowknife and at that time the only dance classes available were highland dancing, which I was not very interested in. 

In my early 20s while living in Vancouver, I took classes in contemporary dance and was fortunate to land a small part in the Karen Jameison Dance company for a piece called The River. The River was about rivers and connection between the reality of a real and physical outdoor river and the different reality of “the river within.” It was both a piece of art and outreach for the community. It included working with the S’pak’wus Slu’lum Dancers of the Squamish Nation. Somewhat ground-breaking for 1998.

From there I was hooked and wanted to do more in dance. I studied a lot and took many classes. Fast forward to now, I have been involved with productions and performances with Crimson Coast Dance for more than 15 years and greatly appreciate the talent and innovation that Artistic Director Holly Bright has brought to this community. She is amazing and very supportive of artists in Nanaimo.

How did this international exchange come about?

The Nordic/Nanaimo exchange is one of the innovative projects Holly created. At the height of the pandemic, funded by BC Arts Council and Made In BC, Crimson Coast Dance embarked on a project that explored the ways in which Nanaimo artists could participate in online exchanges. 

Two artists in Nanaimo – myself and Genevieve Johnson – were introduced to artists from Europe and supported through this international exchange. My collaborator, Mårten Spångberg, is a Swedish artist living and working in Berlin. An extension of that exchange is funded by Canada Council for the Arts – Digital Now.

What brought Mårten and myself together – and I quote Mårten here – is “questions around climate change, ecology and the influence contemporary society has on its environments. We are not interested in making art about the ecological crises or informing our audience about the urgency that climate change implies, but instead through our research develop work that in itself proposes, practices and engages in alternative ecologies.”

We share an understanding that art is a unique place, in the sense of practice, activation, performance and event, through which alternative ecologies can emerge and be probed and analyzed.

Tell us about the launch event.

We are launching the digital art installation that Mårten and I created on April 26 at The Attic at Black Rabbit Restaurant. The event is free to attend but people must sign up as seating is limited. I produced video art with soundscapes that I recorded mixing field recordings with voice and instrumentation. Marten explores text, imagery and AI.

My focus is on the evolving and ongoing process of how we communicate with each other and to nature within a digital context.

During our collaboration, Mårten and I talked about networks, though not just the expansive digital network of the internet but of nature. We shared thoughts on mycelium, a network of fungal threads or hyphae, that lately has received much attention on the importance of its function for the environment, including human beings.

Building off this concept, ideas of digital and ecological landscapes being connected emerged. From this we worked both collaboratively and individually to produce material for this digital project. Mårten will be there via Zoom as well and we will talk about this two-year process and the work we created together.
