Boeing launched its Starliner CST-100 commercial crew spacecraft to the International Space Station (ISS) for the first time on Friday morning in an uncrewed test, and while an error with the onboard mission clock meant that the Starliner didn’t reach its target orbit as intended and subsequently didn’t have enough fuel on board to actually meet up and dock with the ISS, it’s still doing as much testing as it can to complete other mission objectives. One of those objectives is landing the Starliner spacecraft, and Boeing and NASA have scheduled that landing for Sunday at 7:57 AM EST (4:57 AM PST).
The landing will take place at White Sands, New Mexico, and will involve a controlled de-orbit and descent of the Starliner capsule. The spacecraft will begin its de-orbit burn at 7:23 AM EST if all goes to plan, and NASA will begin a live broadcast of the entire landing attempt starting at 6:45 AM EST (3:45 AM PST) on Sunday morning if you want to tune in to the stream embedded below.
Boeing and NASA held a press conference today to provide updates about the mission status after the unplanned mission timer incident on Friday. Boeing SVP of Space and Launch Jim Chilton said during the conference that the team has managed to successfully run a number of its test objective with the mission despite the setback, including extending the docking system to see that it performs as expected, and testing the abort system on board the crew capsule.
The landing is another key test, and could even be more crucial to crew safety in terms of its execution. Both NASA and Boeing have said that were astronauts on board the Starliner during this mission, the mission clock timer incident that occurred would not have put them in any actual danger at any time. Problems with the automated landing sequence would be a different story, potentially – though astronauts are trained to do everything manually in case of any issues encountered while they’re actually in the spacecraft.
Should anything warrant skipping the first attempt at landing tomorrow, NASA and Boeing have a back-up landing opportunity about eight hours after the first. Tune in tomorrow to see how this spacecraft, which will still hopefully carry its first human passengers next year, does with its landing maneuvers.
SpaceX Delays Launch of Falcon 9 Carrier Rocket With Starlink Satellites by a Day – Gadgets 360
SpaceX has cancelled the planned launch of a Falcon 9 carrier rocket with 60 Starlink satellites.
“Auto-abort at T-1:24 ahead of tonight’s Falcon 9 launch of Starlink; next launch opportunity is tomorrow, March 1 at 8:15 p.m. EST [03:15 GMT on Tuesday],” SpaceX said on Twitter on Sunday.
Auto-abort at T-1:24 ahead of tonight’s Falcon 9 launch of Starlink; next launch opportunity is tomorrow, March 1 at 8:15 p.m. EST
— SpaceX (@SpaceX) March 1, 2021
The company did not specify the reasons behind the delay.
The Falcon 9 rocket was supposed to lift off from the Cape Canaveral (Kennedy) Air Force Station in Florida at 01:37 GMT (7:07am) on Monday.
The mission aims to put 60 Starlink satellites into orbit. If successful at its next launch opportunity, it will expand SpaceX’s fleet of broadband relay satellites to include over 1,200 (some of them are prototypes that are no longer in service).
The Starlink project seeks to provide affordable access to broadband Internet connection across the world.
Earlier in February, SpaceX reportedly completed an equity funding round of $850 million (roughly Rs. 6,190 crore) that sent its valuation to about $74 billion (roughly Rs. 5,39,000 crore).
SpaceX raised the funds at $419.99 (roughly Rs. 30,600) a share and the latest funding round represents a jump of about 60 percent in the company’s valuation from its previous raise, which valued it at $46 billion (roughly Rs. 3,35,000 crores), as per the report.
A prototype of SpaceX’s Starship rocket, the SN9, exploded earlier in February during a landing attempt after a high-altitude test launch in a repeat of an accident that destroyed a previous test rocket.

SpaceX aborts launch of Falcon 9 rocket carrying Starlink satellites – Space.com
A veteran SpaceX rocket suffered a launch abort just minutes before liftoff Sunday night (Feb. 28) while attempting to launch a new fleet of the company’s Starlink internet satellites.
The Falcon 9 rocket was less than 90 seconds away from launching 60 Starlink satellites into orbit from Pad 39A of NASA’s Kennedy Space Center in Cape Canaveral, Florida when it experienced the automatic abort, SpaceX said.
“Overall, the vehicle and payload are healthy and remain in good health,” SpaceX production supervisor Andy Tran said during live launch commentary. “The next launch opportunity is tomorrow, March 1, at 8:15 Eastern time.”
Sunday night’s launch abort is the latest delay for this particular Starlink mission. It was originally scheduled to fly earlier in February, but was delayed due to hardware issues and poor weather.
The mission, called Starlink 17, will now be SpaceX’s 20th Starlink mission and the company’s sixth launch of 2021. SpaceX currently has more than 1,000 Starlink satellites in orbit as it builds a megaconstellation capable of providing global high-speed internet coverage, particularly to remote or underserved locales.
The Falcon 9 rocket for Starlink 17 includes a first stage booster that has flown seven times so far. It launched the Iridium-8 and Telstar 18 Vantage satellite missions, as well as five separate Starlink flights.
The booster is poised to be the third Falcon 9 booster to fly eight times and, if all goes well, will land on the drone ship “Of Course I Still Love You” in the Atlantic Ocean so it can be recovered. SpaceX’s current Block 5 Falcon 9 rockets are designed to fly up to 10 times as part of the company’s reusability program to lower launch costs.
In addition to the booster, the Starlink 17 mission also includes reused payload fairings (its clamshell-like nosecone). One half is making its fourth flight while the other is on its third. Two SpaceX recovery ships, the GO Searcher and GO Navigator, are stationed off shore to recovery the fairings for later reuse as well.
According to the U.S. Space Force’s 45th Weather Squadron, there is a 70% chance of good weather for a SpaceX launch on Monday night.

Let 'er buck: Study suggests horses learn from rodeo experience, grow calmer – Nanaimo News NOW
Horses have all kinds of ways of showing they’re unhappy, Pajor said. They might move back and forth, chew their lips, swish their tail, defecate, roll their eyes, paw the ground, toss their head, or rear up in protest.
The researchers found that the more people were around them, the more likely the horses were to show unease. That’s probably because they spend most of their time in fields and pastures and aren’t used to the bustle, Pajor said.
The other factor that affected behaviour was experience. If it wasn’t their first rodeo, the horses were much less likely to act up.
“We didn’t see a lot of attempts to escape. We didn’t see a lot of fear-related behaviours at all,” Pajor said. “The animals were pretty calm.
“The animals that had little experience were much more reactive than the animals that had lots of experience.”
There could be different reasons for that, he suggested.
“We don’t know if that’s because they’re used to the situation or whether that’s because of learned helplessness — they realize there’s nothing they can do and just give up.”
Pajor suspects the former.
“When the cowboys came near the horses, they would certainly react and you wouldn’t really see that if it was learned helplessness.”
The researchers also noted that the horses’ bucking performance, as revealed in the score from the rodeo judges, didn’t seem to be reduced by repeated appearances as it might be if the animals had become apathetic.
That doesn’t necessarily mean the horses are having a good time, said Pajor, who’s also on the Stampede’s animal welfare advisory board. There are a couple of ways of interpreting active behaviour in the chute, he said.
“An animal might be getting excited to perform. Or an animal might be having a fear response.”
“Understanding if animals like to do something is a tricky thing to do.”
Pajor knows there are different camps when it comes to rodeos and animals.
“People have very strong opinions on the use of animals for all kinds of reasons. I think no matter what we’re going to use animals for, we really need to make sure that we treat them humanely.
“My job is to do the research to understand the animals’ perspective.”
