This week is panning out to be quite dramatic with NASA set to test its Mars Helicopter and SpaceX taking astronauts to the ISS on its Crew Dragon spacecraft. In addition to those events, SpaceX is also expected to launch the Starship SN-15 mission which will see the firm attempt to land the craft following NASA’s decision to pick Starship as the human landing system for its missions to the Moon from 2024.

There are no rocket launches listed for Monday, however, Elon Musk did put out a tweet explaining that SpaceX is aiming to launch Starship SN-15 this week, therefore, Monday is the earliest time we will see the launch. This is the first Starship launch since NASA chose the vehicle for its human landing system on the Artemis missions so SpaceX should have a bit more motivation to get the landing right this time around.
Aiming to launch next week

While this series is called This Week in Rocket Launches, it’s probably worth mentioning that NASA is looking to fly the Ingenuity Mars Helicopter from Monday at 3:30 a.m. EDT (12:30 a.m. PDT). Data from the autonomous flight will take time to get back to Earth and a live stream is due to start at 6:15 a.m. EDT (3:15 a.m. PDT). If the flight takes place, NASA will hold a briefing at 2 p.m. EDT (11 a.m. PDT) to apprise us of how the mission went.

There’s only one event set for Tuesday and that is ExPace’s planned launch of the Kuaizhou KZ-1A with the Jilin Gaofen 2D satellite (Jilin 28) aboard. We’ve spoken several times about this launch in older issues of TWIRL but briefly, this satellite will capture high-resolution full-colour images from 535 km and will work within the Jilin 1 constellation that’s already in orbit.

Thursday will be one of the most interesting days of the week with SpaceX carrying out the Crew-2 Dragon mission which will carry NASA astronauts Shane Kimbrough, Megan McArthur, ESA astronaut Thomas Pesquet, and JAXA astronaut Akihiko Hoshide to the international space station. This Dragon capsule is named Endeavour after the Space Shuttle and was the first of the dragon capsules to carry a crew.
Interestingly, the ISS only got new arrivals two weeks ago so when the four new astronauts arrive there will 11 people on-board which is the highest number that has ever been on the space station at once, though, it’s not the highest number of people that have been in space at one time. Luckily for those on board, four of the astronauts will be departing on the SpaceX Crew-1 on April 28 bringing the ISS crew size to 7.

On Sunday there will be two missions. Roscosmos is looking to launch the Resurs-P 4 satellite from Baikonur atop a Soyuz 2.1b rocket and OneWeb will have 36 of its satellites put into orbit by a Starsem-owned Soyuz 2.1b rocket. The Resurs-P satellite will conduct Earth observation for Russian government agencies while the OneWeb satellites will make up a constellation providing internet for people on Earth and flying in planes.
