Northrop Grumman's Cygnus cargo resupply vehicle will be captured by the robotic CANADARM-2 on the International Space Station.

The Soyuz MS-17 spacecraft will dock to the International Space Station with crew members Sergey Ryzhikov, Sergey Kud-Sverchkov, and Kate Rubins.

OSIRIS-REx will move into position to collect a sample of asteroid Bennu's surface material. The spacecraft's sampling arm will then touch the surface for five seconds as part of the Touch-And-Go (TAG) sampling maneuver.

The Soyuz MS-16 spacecraft will undock from the International Space Station with crew members Chris Cassidy, Anatoly Ivanishin, and Ivan Vagner.

A SpaceX Crew Dragon spacecraft will dock to the International Space Station with crew members Mike Hopkins, Victor Glover, Soichi Noguchi, and Shannon Walker.

Two cosmonauts will perform a spacewalk on the International Space Station.

A Dragon spacecraft filled with resupply cargo will dock with the International Space Station. This will mark the first time that two SpaceX Dragon spacecraft are docked with the Station at the same time.

The core stage for NASA's first SLS rocket will perform a Green Run hotfire test on the B-2 test stand at NASA Stennis.

After collecting several samples of the asteroid Ryugu, and after dropping several objects on its surface, Hayabusa-2 will leave Ryugu in December 2019 to bring back the samples it has collected on the asteroid. The capsule containing them should land in the Australian desert just like the Hayabusa-1 mission.

NASA's Perseverance Mars rover will land at Jezero crater on Mars. The mission will seek signs of habitable conditions on Mars in the ancient past, and will also search for evidence—or biosignatures—of past microbial life.

Russia will remove the Pirs module from the International Space Station to free the location for the future Nauka module. The undocking will be performed by a Progress cargo craft. The two vehicles will then be deorbited – burning up in Earth's atmosphere.

The new Russian Nauka module will allow Russia to have an additional scientific module aboard the International Space Station. Nauka will dock at the port of the old Pirs module.

Callisto is a prototype vehicle for a reusable rocket being developed by CNES, in cooperation with DLR, and JAXA. It will liftoff from the Kourou base in French Guiana for a suborbital flight, before returning to land next to the launch pad.

ExoMars is a Martian rover of the European Space Agency that will land in the region of Oxia Planum. The rover will investigate the local geology and search for signs of past and present life.

The OSIRIS-REx spacecraft will return a sample of the asteroid Bennu to Earth. The sample will land via parachute in the Utah desert.

Thémis is a reusable launcher demonstrator developed by CNES and ESA. It must liftoff from Kourou with three methane-powered Prometheus engines, and return to land on a recovery barge.
