One of the craters in the area called Jau

NASA celebrated the 11th anniversary of its Mars Rover Curiosity’s arrival on Mars with relief, as in recent days, the oldest rover still in operation on the red planet has just completed its most difficult ascent due to the terrain conditions. Curiosity reached an area filled with impact craters called Jau by climbing a 23° slope where there were obstacles such as slippery sand and rocks that could damage its wheels. The mission team managing route planning spent intense weeks deciding on several detours to limit danger and wear.

Northrop Grumman’s Cygnus spacecraft, launched last Wednesday, August 2, has just reached the International Space Station and was captured by the Canadarm2 robotic arm. Astronaut Woody Hoburg, assisted by his colleague Frank Rubio, will soon begin the slow maneuver to move the Cygnus until it docks with the Station’s Unity module after about two hours.

A few hours ago, Northrop Grumman’s Cygnus spacecraft blasted off atop an Antares rocket from the Mid-Atlantic Regional Spaceport (MARS), part of NASA’s Wallops Flight Facility (WFF) on Wallops Island. After about nine minutes it successfully separated from the rocket’s last stage and went en route to its destination. This is the mission called NG-19 or CRS NG-19 to transport supplies to the International Space Station for NASA.

A little while ago, SpaceX’s Dragon spacecraft ended its CRS-28 (Cargo Resupply Service 28) mission for NASA splashing down smoothly off the Florida Coast. The Dragon left the International Space Station about 22 hours earlier. For SpaceX, this was the 8th mission of the 2nd contract with NASA to transport supplies to the Station with the new version of the Dragon cargo spacecraft.

Shortly after the splashdown, SpaceX’s recovery ship went to retrieve the Dragon to transport it to the coast. The cargo brought back to Earth will be delivered to NASA within a few hours. The Dragon spacecraft reached the International Space Station on June 6, 2023.

An article published in the journal “Nature” reports evidence that about 200 years ago, Sagittarius A*, or simply Sgr A*, the supermassive black hole at the center of the Milky Way, had a period of intense activity during which it swallowed considerable amounts of gas and dust. A team of researchers led by Frédéric Marin of the Astronomical Observatory of Strasbourg, France, used in particular data collected by the IXPE space telescope to examine the polarization of X-ray light emitted by bright large molecular clouds close to Sgr A*. The conclusion is that their out-of-normal brightness must have been due to the fact that they are reflected emissions produced by some kind of powerful and short-lived flare of the supermassive black hole that occurred about 200 years ago.
