SpaceX
Elon Musk’s house firm is about to launch the Crew-3 mission for NASA on Wednesday night, within the fifth SpaceX crewed mission previously 18 months.
Crew-3 is about to carry off from launchpad 39A at NASA’s Kennedy House Middle in Florida at 9:03 p.m. ET. The astronauts are scheduled to reach on the Worldwide House Station on Thursday at 7:10 p.m. ET.
“Every little thing appears like we’re in a superb place to go fly,” SpaceX Vice President William Gerstenmaier advised reporters throughout a prelaunch briefing.
The launch marks SpaceX’s third operational crew launch for NASA thus far, and the primary by the newest addition to its fleet of Crew Dragon capsules, named Endurance by the Crew-3 astronauts. The Crew-3 mission will carry the variety of astronauts SpaceX has launched to 18.
NASA and SpaceX have delayed the Crew-3 launch a number of occasions since its earlier goal, Oct. 30, on account of unhealthy climate within the Atlantic Ocean in addition to a minor medical problem with one of many 4 crew members. The ocean must be calm within the course the rocket is launching, in case a midflight abort results in the capsule splashing down after liftoff. NASA declined to specify extra in regards to the medical problem, citing the astronauts’ private privateness, however mentioned that it was not an emergency and unrelated to the Covid-19 virus.

The Crew-3 mission will carry 4 astronauts, three American and one German: NASA astronauts Raja Chari, Tom Marshburn and Kayla Barron, and European House Company astronaut Matthias Maurer.
Chari, the spacecraft’s commander, was chosen as an astronaut by NASA in 2017. This can be his first spaceflight. He was additionally chosen by NASA as certainly one of its astronauts eligible for future Artemis lunar missions later this decade. Chari is a U.S. Air Power colonel, with greater than 2,500 hours of flight time.
Marshburn, the Crew-3 pilot, was chosen as an astronaut by NASA in 2004. That is Marshburn’s third spaceflight. He has additionally flown on the house shuttle and Russian Soyuz spacecraft. Beforehand Marshburn was a NASA flight surgeon.
Barron is flying as a Crew-3 mission specialist, having been chosen by NASA in 2017. The launch is Barron’s first spaceflight. She graduated from the U.S. Naval Academy in 2010, and holds a grasp’s diploma in nuclear engineering from the College of Cambridge.
Maurer, the newest worldwide astronaut to fly with SpaceX, joined the European astronaut corps in 2015. This can be his first spaceflight as properly.
The spacecraft: Crew Dragon capsule Endurance
The Crew Dragon spacecraft for NASA’s SpaceX Crew-3 mission arrives on the hangar at Kennedy House Middle’s Launch Advanced 39A in Florida on Oct. 24, 2021.
SpaceX
SpaceX developed its Crew Dragon spacecraft and fine-tuned its Falcon 9 rocket underneath NASA’s Industrial Crew program, which offered the corporate with $3.1 billion to develop the system and launch six operational missions.
Industrial Crew is a aggressive program, and NASA additionally awarded Boeing with $4.8 billion in contracts to develop its Starliner spacecraft. Boeing’s capsule, nonetheless, stays in improvement on account of an uncrewed flight take a look at in December 2019 that skilled important challenges.
Crew-3 represents the third of these six missions for SpaceX, with NASA now benefiting from the funding it made within the firm’s spacecraft improvement.
NASA emphasizes that, along with the U.S. having a solution to ship astronauts to house, SpaceX provides the company a cost-saving choice as properly. The company expects to pay $55 million per astronaut to fly with Crew Dragon, versus $86 million per astronaut to fly on a Russian spacecraft. NASA final 12 months estimated that having two non-public firms compete for contracts saved the company between $20 billion and $30 billion in improvement prices.
The corporate accomplished a full gown rehearsal for Crew-3 in October, with the quartet of astronauts working towards suiting up and driving out to the launchpad within the pair of Tesla Mannequin Xs that SpaceX makes use of for crew transportation.
Endurance is a brand new Crew Dragon capsule debuting for this mission. Beforehand, capsules Resilience and Endeavour have flown astronauts, and SpaceX expects so as to add a fourth Crew Dragon early subsequent 12 months.
Crew Dragon is an advanced model of the corporate’s Cargo Dragon spacecraft. Simply as Cargo Dragon was the primary privately developed spacecraft to hold provides to the ISS, so Crew Dragon is the primary privately developed spacecraft to move folks to the station.
Whereas SpaceX has flown a most of 4 folks on every mission up to now, Crew Dragon is designed to hold as many as seven passengers to house at a time.
SpaceX just lately has had incidents with the bathroom on board its Crew Dragon spacecraft, as a hose on Resilience got here unglued through the Inspiration4 mission — though the crew on board didn’t discover the issue through the spaceflight — and the Endeavour capsule that returned the Crew-2 mission earlier this week had an analogous downside. The corporate says it up to date the design of Endurance’s waste administration system previous to Crew-3’s launch, in an effort to right the issue.
Crew Dragon’s parachutes have been additionally some extent of concern, as one of many 4 essential parachutes throughout Crew-2’s return deployed extra slowly than the others. Gerstenmaier advised reporters that regardless of the gradual opening, the parachute carried out as anticipated — emphasizing that Crew Dragon can splashdown underneath three parachutes if wanted. NASA and SpaceX groups inspected the Crew-2 parachutes after recovering them from the water and checked out knowledge from the flight, with Gerstenmaier saying that nothing was out of the extraordinary after the overview.
The corporate plans to proceed to reuse its Crew Dragon capsules, having already carried out so with the Crew-2 and Inspiration4 missions.
The rocket: Falcon 9
SpaceX briefly take a look at fires its Falcon 9 rocket with Crew Dragon capsule Endurance on high in preparation for the Crew-3 launch.

Crew Dragon will launch on high of SpaceX’s Falcon 9 rocket, with the booster — the massive, decrease part of the rocket — anticipated to land on the corporate’s autonomous barge within the Atlantic Ocean.
SpaceX carried out a static hearth of the rocket on Oct. 28, throughout which its 9 engines have been fired for a number of seconds whereas it stood on the launchpad.
Falcon 9 has change into the workhorse of SpaceX’s rising fleet. The rocket stands at almost 230 ft tall and is able to launching as a lot as 25 tons to low Earth orbit. The Falcon 9 sequence is certified to fly as much as 10 flights, and SpaceX continues to push the boundary of reusability with satellite tv for pc launches.
The launch plan

4 hours earlier than liftoff, the astronauts will swimsuit up. About half an hour later, the crew will stroll out to their Mannequin X rides, full with NASA logos, which is able to drive from the astronaut quarters out to the launchpad.
With 2½ hours to go, the astronauts will strap into their seats in Crew Dragon and start checking that every one methods are good to go. Then, with slightly below two hours till launch, the hatch to the spacecraft can be closed.
SpaceX will start loading the rocket with gasoline 35 minutes earlier than launch, initiating a closing sequence of processes and checks.
A couple of minutes after liftoff, the Falcon 9′s booster stage will return and try to land on the corporate’s barge stationed within the Atlantic Ocean.
If something have been to go fallacious within the final half-hour earlier than the launch and even through the launch, Crew Dragon will abort and hearth its emergency escape system. The corporate examined that system with nobody contained in the spacecraft. In that take a look at, SpaceX triggered the system throughout probably the most intense a part of the launch to point out that it may very well be carried out at any time.
After arriving on the ISS, Crew-3 will carry out a full period mission, spending about six months on board.
