In just 57 days, NASA’s diligent rover will attempt to land on Mars. Mission regulators say it will be a “seven-minute terror” as this new depiction proves dramatic.

Digital animation produced by NASA’s Jet Propulsion Laboratory depicts the key events of the rover’s entry, descent and landing (EDL). The video is over three minutes long Length, which is not less than the landing stage, should be seven Minutes. The diligence was launched on July 30th, And will perform EDL in February. 18, 2021 at 3:30 pm EST.

The $ 2.7 billion rover will land in the Xero gorge, the site of the former lake and river delta. With its many tools, diligence will look for signs of microbial life, study Mars weather and geography, and collect samples for future work on recovery. Rover ingenuity, A small helicopter is poised to become the first man-made aircraft to fly in an alien world.

Of course, perseverance must land if any of this is to happen. In fact, Mars is infamous for ending before it even gets a chance to start — ESA. Failure The latest example of Schiaparelli work in 2017.

The first phase of the EDL will see the evacuation of the ship phase delivering solar panels, radios and fuel tanks used during the Red Planet voyage. Descent status, as Diligence Approaching the atmosphere, shoot small thrusts at its rear to ensure the vehicle is properly aimed and the heat shield is facing forward. Descendant status will see the rover later Go through the thin Martian atmosphere at a speed of 12,000 miles (19,312) kph), According to To NASA. If this condition is to go as planned, the interior of the craft should not be warmer than room temperature.

A supersonic parachute will be deployed if the descent level drops to at least 1,000 mph (1,609 kph). NASA is about to launch a new system Limit trigger, To determine the most optimal moment to deploy the parachute, which should occur 240 seconds after atmospheric entry. The heat shield is then dropped as desired Will not be anymore Required For the first time Mars is exposing the rover to the atmosphere.

Another new technology, called Landscape-relative navigation, Will use video cameras and maps to select a safe place to land.

At maximum, the parachute will slow the vehicle down to 200 mph (322 kph), Running descent required. At 6,900 feet (2,100 m) above the surface of the diligence, the rocket-powered descent level enters and slows down the craft at a highly manageable 2 mph (3.2 km.). A ski crane would then slowly lower to 2,260Pound (1,025-Kilograms) Rover on the surface, which is 21 feet long (6.4-Meters long) Cables. The ski crane will cut the cables as soon as it senses a landing and then zip clearly from the target site.

Only Then Is real The fun begins as the rover is free to explore the surface of Mars. The diligent work is expected to last two years, but as the forerunner has shown, it is cWill last a long time. For example, NASA’s Curiosity rover landed on Mars in 2012, and it is still strong. We look forward to the work of perseverance, but first things first: it must escape the seven-minute terror.

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

Published

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.
