NASA is a step closer to returning astronauts to the Moon in the next five years following this successful “hot fire” test of flight engine No. 2062 on the A-1 Test Stand at Stennis Space Center in Mississippi. This April 4, 2019 test caps more than four years of testing for the RS-25 engines that will help power the first four missions of the Space Launch System rockets. It also concludes a 51-month test series that demonstrated RS-25 engines can perform at the higher power level needed to launch the super heavy-lift SLS rocket.

In this video we present an overview of Denmark, our workshop, SpacePort Nexø and finally the launch site and flight path of Nexø II, combined with the expected path as predicted by our weather model. The orange line is the actual flight path and the red line is the predicted path.

Rocket Lab dicit:

DARPA’s Radio Frequency Risk Reduction Deployment Demonstration (R3D2) mission […] intends to space-qualify a prototype reflect array antenna to improve radio communications in small spacecraft. The antenna, made of a tissue-thin Kapton membrane, packs tightly inside the small satellite for stowage during launch, before deploying to its full size of 2.25 meters in diameter once it reaches low Earth orbit. This high compaction ratio enables larger antennas in smaller satellites, enabling satellite owners to take advantage of volume-limited launch opportunities while still providing significant capability. The mission could help validate emerging concepts for a resilient sensor and data transport layer in low Earth orbit – a capability that does not exist today, but one which could revolutionize global communications by laying the groundwork for a space-based internet.

This is a simulation of a twenty-five-and-a-half-day mission from roll-out to recovery of the first integrated flight test of NASA’s Orion spacecraft and the Space Launch System rocket, launching from the agency’s Kennedy Space Center in Florida. This uncrewed mission will be the first in a planned series of exploration missions beyond the moon, signaling what astronauts who dare to operate in deep space will experience on future flights.

Expedition 59 is the 59th Expedition to the International Space Station, started on 14 March 2019 with the arrival of the Soyuz MS-12 spacecraft carrying Aleksey Ovchinin, Nick Hague and Christina Koch. Ovchinin and Hague were originally meant to fly to the ISS aboard Soyuz MS-10, but had to return minutes after takeoff due to an unforeseen anomaly. The three will subsequently transfer to the Expedition 60 crew, with Ovchinin as commander, after the undocking of the Soyuz MS-11 spacecraft, scheduled for July 2019.

Researchers on Expedition 59 will conduct experimentation on tissue chips because the microgravity environment can replicate the effects of aging and disease. The expedition will also conduct experiments on regolith stimulants and Earth’s atmospheric carbon cycle. Lastly, the expedition will also test Astrobee robots designed to conduct routine chores aboard the ISS.
