The Land3U team consists of one PhD, and five MSc students from Cranfield University’s Astronautics and Space Engineering course. The team’s microgravity experiment proposed to simulate the landing of a 3U CubeSat on an asteroid, as part of ESA Academy’s Drop Your Thesis! 2018 Programme. For the team, the low gravity conditions of the Drop Tower in Bremen, Germany, are perfect as it resembles the gravity conditions surrounding the asteroids. Their CubeSat experiment sought to provide valuable insights into the engineering challenges that must be addressed by future asteroid missions; in particular when attempting to land on the surface of such low-gravity bodies.

Timelapse of the Russian Progress MS-10 cargo spacecraft launched on 16 November 2018 at 18:14 GMT from Baikonur cosmodrome, Kazakhstan, taken by ESA astronaut Alexander Gerst from the International Space Station.
The spacecraft was launched atop a Soyuz rocket with 2564 kg of cargo and supplies. Flying at 28 800 km/h, 400 km high, the International Space Station requires regular supplies from Earth such as this Progress launch. Spacecraft are launched after the Space Station flies overhead so they catch up with the orbital outpost to dock, in this case two days later on 18 November 2018.
The images were taken from the European-built Cupola module with a camera set to take pictures at regular intervals. The pictures are then played quickly after each other at 8 to 16 times normal speed. The video shows around 15 minutes of the launch at normal speed.
The Progress spacecraft delivered food, fuel and supplies, including about 750 kg of propellant, 75 kg of oxygen and air and 440 l of water.
Some notable moments in this video are:
00:07 Soyuz-FG rocket booster separation.
00:19 Core stage separation.
00:34:05 Core stage starts burning in the atmosphere as it returns to Earth after having spent all its fuel.
00:34:19 Progress spacecraft separates from rocket and enters orbit to catch up with the International Space Station.

Europe’s Vega launch vehicle operating from Europe’s Spaceport in Kourou, French Guiana, has a flawless record.
Vega serves a wide range of missions and payload configurations, responding to different market opportunities. It is the ideal launcher for most scientific and Earth observation missions, benchmarked to loft 1500 kg into a 700 km-altitude circular orbit at 90° inclination.
Based on this success a more powerful #Vega, Vega-C, now in development is set to launch in mid-2019 offering greater performance at no additional cost.
Vega-C shares technology with Europe’s other new launcher Ariane 6. The P120C solid fuel motor will be used as the first stage for Vega-C and two or four will be used as strap-on boosters for Ariane 6.

Orion is NASA’s spacecraft for carrying astronauts on exploration missions to the Moon and beyond. When Orion returns to Earth from space, it will be slowed by parachutes before splashdown. Here, NASA’s recovery team and the U.S. Navy practice recovering a test Orion capsule from the ocean waters. Bonus: stunning views of the sunset in the Pacific off the coast of California!
This footage was captured on Nov. 1, 2018, during Underway Recovery Test-7 (URT-7) — one in a series of tests that NASA’s Exploration Ground Systems Recovery Team and the U.S. Navy are conducting: https://go.nasa.gov/2Ph6Mnr. These tests verify and validate procedures and hardware that will be used to recover the Orion spacecraft after it splashes down in the Pacific Ocean following deep space exploration missions.
Space weather describes the changing environment throughout the Solar System, driven by the energetic and unpredictable nature of our Sun. Solar wind, solar flares and Coronal Mass Ejections can result in geomagetic storms on Earth, potentially damaging satellites in space and the technologies that rely on them, as well as infrastructure on the ground.
ESA’s future Lagrange mission will keep constant watch on the Sun. The satellite, located at the fifth Lagrange point, will send early warning of potentially harmful solar activity before it affects satellites in orbit or power grids on the ground, giving operators the time to act to protect vital infrastructure.
ESA is now working with European industry to assess options for the spacecraft and its mission, with initial proposals expected early in 2020.
Our star dominates the environment within our Solar System. Unpredictable and temperamental, the Sun has made life on the inner-most planets impossible, due to the intense radiation and colossal amounts of energetic material it blasts in every direction, creating the ever-changing conditions in space known as ‘space weather’.

Sir Michael Atiyah este matematicianul englez (89 de ani) care anunța recent că a rezolvat celebra ipoteză Riemann (premiu 1 milion $). După ce și-a prezentat calculele, matematicienii au căzut de acord: calculele lui nu sunt o demonstrație, deci premiul rămâne în picioare.
Acum, Sir Michael Atiyah “lovește” din nou, de data aceasta in fizică. Într-un alt articol (https://goo.gl/oQyubJ), el susține că a găsit un principiu prin care se pot deduce constantele “fundamentale” din fizica, și exemplifică cu calculul constantei de structura fina (~1/137).
