The DSCOVR (Deep Space Climate Observatory) satellite was launched a few hours ago on a SpaceX Falcon 9 rocket from the Space Launch Complex 40 (SLC-40) at Cape Canaveral. The spacecraft successfully separated from the rocket’s last stage after about half an hour and inserted in the trajectory that will bring it to its destination. It also deployed its solar panels and sent the first signals, confirming that it’s working properly.

DSCOVR will be placed in an area called L1, about a half million kilometers (about 930,000 miles) from Earth, where the planet and the Sun’s gravity are balanced. There it will begin its mission of observation of the solar wind after the test period, that will last about 40 days.

Today the suborbital test of IXV (Intermediate eXperimental Vehicle) was conducted. It’s an ESA experimental spacecraft that is designed to verify the some rentry technologies. IXV was launched on a Vega rocket in the launch indicated as VV04 from the Kourou space center in French Guyana.

The final purpose for ESA is to build a spacecraft capable of returning to Earth autonomously. Over the years, ESA has built various types of spacecraft, including cargo ships, but none are able to return to Earth. For this reason, in 2002 it was decided to develop the technologies needed in order to build a spacecraft capable of bringing cargo from the International Space Station or from other missions in orbit.

A few hours ago the SpaceX Dragon spacecraft ended its CRS-5 (Cargo Resupply Service 5) mission for NASA splashing down without problems in the Pacific Ocean about 400 km (about 260 miles) off the coast of California. The Dragon left the International Space Station yesterday evening, American time.

Shortly after splashing down, the Dragon was recovered by the SpaceX boats that will transport it to the coast. The cargo brought back to Earth should be delivered to NASA today. The Dragon spacecraft reached the International Space Station on January 12, 2015.

A the 18th Annual Federal Aviation Administration (FAA)’s Commercial Space Transportation Conference, Bradford Tousley, director of DARPA’s Tactical Technology Office showed the progress of the project ALASA (Airborne Launch Assist Space Access), a system to launch small satellites using an airplane instead of a carrier rocket. This would greatly reduce the cost, currently very high, down to one million dollars for just under 50 kg (100 pounds).

Nearly two years after presenting the best map ever made of the cosmic microwave background radiation, ESA revealed another map created using data collected by the Planck Surveyor space probe between 2009 and 2013. This new map shows the polarization of the cosmic microwave background radiation dating back to the early stages of the universe. It shows that the first stars started forming about 550 million years after the Big Bang, 100 million years later than previously thought.
