The rocket is scheduled to launch today at 11:11 a.m. EDT (1511 GMT). If all goes well, Cygnus should arrive at the space station this Saturday to deliver 7,635 lbs. (3,463 kilograms) of supplies. — Hanneke Weitering

Wednesday, April 19, 2017: Astronaut Thomas Pesquet captured star trails swirling around the Earth in this photo he took from the International Space Station. "It's not a star shower, but sure looks like it," Pesquet tweeted on Sunday (April 16). "Flying at 28,000 km/h [17,400 mph] allows us to see the starry sky parading before our eyes like a mobile in a children's room... except life-size." — Hanneke Weitering

Happy Birthday, Canadarm2!

NASA

Thursday, April 20, 2017: Canadarm2, a robotic arm outside the International Space Station, turns 16 years old this week! The 58-foot-long (18 meters) robot hitched a ride on the space shuttle Endeavour with mission STS-100 on April 19, 2001. Canadian astronaut Chris Hadfield and NASA astronaut Scott Parazynski completed the installation of Canadarm2 with the mission's second spacewalk on April 24. In this photo, NASA astronaut Stephen Robinson rides Canadarm2 during the STS-114 mission in 2005. — Hanneke Weitering

Happy installation anniversary, Canadarm2! — Hanneke Weitering

Deploying Hubble

NASA

Tuesday, April 25, 2017: On this day in 1990, NASA's space shuttle mission STS-31 deployed the Hubble Space Telescope into orbit about 382 miles (615 km) above the Earth. The telescope was launched to capture images of the cosmos with unprecedented clarity, but a flaw in its mirror left the telescope nearsighted. It was later repaired by astronauts during a servicing mission in 1993. — Hanneke Weitering
