Expedition 65 mission is NASA's 65th and busiest crewed expedition to the International Space Station (ISS) yet.

The mission started with seven crew members on board on April 17, Space.com said. Three astronauts from the Soyuz MS-18 spacecraft plus four astronauts from SpaceX's Crew-1 mission. A second SpaceX Crew Dragon ship landed on April 24, with four more Crew-2 members, bringing the ISS population to 11 people - about double the average crew size.

Today, the four new SpaceX Crew-2 astronauts joined the Expedition 65 crew, bringing the station population to 11.

The whole Expedition 65 crew of 11 gathered for a picture on board the International Space Station, as shared by NASA. NASA astronaut Mark Vande Hei plus cosmonauts Oleg Novitsky and Pyotr Dubrov arrived on the Soyuz MS-18.

The SpaceX Crew-2 astronauts (not in order) are: ESA's Thomas Pesquet, JAXA's Akihiko Hoshide, NASA's Megan McArthur, and NASA's Shane Kimbrough. JAXA's Soichi Noguchi, NASA's Michael Hopkins, and NASA's Shannon Walker and Victor Glover are also seen in the photo.

Only seven crew members remained on board the International Space Station after the SpaceX Crew-1 astronauts returned to Earth. The Expedition 65 crew - one ESA astronaut, a JAXA astronaut, two cosmonauts, and three NASA astronauts - poses for a portrait, which NASA shared on its website.

This image from April 24, 2021, shows the SpaceX Crew Dragon Endeavour as it approached the International Space Station less than one day after launching from Kennedy Space Center in Florida. The SpaceX Crew-2 astronauts, Commander Shane Kimbrough and pilot Megan McArthur with astronauts Akihiko Hoshide of the Japan Aerospace Exploration Agency and Thomas Pesquet of the European Space Agency joined the Expedition 65 crew shortly after docking to the Harmony module's forward-facing international docking adapter.

The SpaceX Crew Dragon Endeavour arrived on the International Space Station against a breathtaking vista of Earth on April 24. Akihiko Hoshide, Megan McArthur, Shane Kimbrough, and Thomas Pesquet were transported to the International Space Station to join Expedition 65.

Trash Talks

iss065e007768 (April 27, 20211) --- The trash-filled ISS Progress 75 (75P) resupply ship, with the full Moon above the Earth's horizon, is pictured separating from the International Space Station shortly after undocking from the Zvezda service module. The 75P had spent just over a year attached to Zvezda.

After a year docked with the International Space Station's Zvezda service module, the Russian Progress 75 (75P) cargo resupply ship, loaded with garbage, has departed from the orbiting lab's Zvezda service module. Progress 75 arrived in the station on April 25, 2020, and left on April 27, 2021, safely burning up in Earth's atmosphere.

The newly installed MpLM (Multi-purpose Laboratory Module), known as the Nauka module, docked to the Zvezda port on ISS.

Russia launched its new Multipurpose Laboratory Module, commonly known as Nauka, to the International Space Station during Expedition 65. On July 29, 2021, Nauka docked with the ISS, after which it briefly misfired its engines, sending the station spinning in orbit. According to NASA, ISS flight controllers could correct the problem, and the astronauts were not in danger.

The Russian portion of the orbiting lab will use Nauka as a scientific module. A view of Russia's Nauka module docked with the International Space Station on July 29.
