JAXA, the Japanese space agency, confirmed that its space probe Akatsuki has successfully accomplished the maneuvers to allow it to enter the orbit of the planet Venus. These maneuvers took place exactly five years after the failure of the first attempt. The orbit is significantly different from the one programmed for the mission and JAXA engineers are assessing it to schedule some additional maneuvers. However, there’s optimism about the possibility of carrying out the scientific mission Akatsuki was built for.

A few hours ago the Orbital ATK’s Cygnus spacecraft blasted off atop an Atlas V rocket from Cape Canaveral. After about twenty minutes it successfully separated from the rocket’s last stage and got in route. This is its fourth official mission, Orbital-4 or simply Orb-4 as well as CRS OA-4, to transport supplies to the International Space Station for NASA.

NASA released the first very high resolution photographs showing close-ups of ​​the dwarf planet Pluto’s surface. These are images captured by the New Horizons space probe during its extraordinary July 14, 2015 flyby. In recent months, NASA already received high-resolution photographs but these ones are part of a series of shots that was intended to capture the details of Pluto’s surface, in this case the area called Sputnik Planum.

An article published in the journal “Astrophysical Journal” describes the discovery of the faintest galaxy in the early universe. According to this study, this galaxy was born when the universe was “only” about 400 million years old and for this reason was nicknamed Tayna, which means “first born” in the Aymara language. To detect its light the gravitational lensing effect of a galaxy cluster was used. That allowed to capture the extremely dim light of a total of 22 ancient galaxies using the Hubble and Spitzer space telescopes.

A few hours ago ESA’s LISA Pathfinder space probe was successfully launched atop a Vega rocket from the Kourou space center in French Guiana. After about an hour and 45 minutes it separated from the rocket’s upper stage and activated to begin its long journey thanks to its propulsion module.

LISA Pathfinder entered an elliptical orbit where it will make a series of maneuvers that within a few weeks will take it to the area called L1, where the gravity of the Earth and the Sun get balanced with the other forces acting on the probe. The propulsion module will be disconnected after exhausting its function and the probe will remain in the L1 area, about 1.5 million kilometers (about 900,000 miles) from Earth.
