NASA’s new mission to study black holes set for 2020 launch
Washington: NASA said on Wednesday it plans to launch in 2020 a $188 million mission that will allow astronomers to explore, for the first time, the hidden details of some of the most extreme and exotic astronomical objects, such as stellar and supermassive black holes, neutron stars and pulsars.Objects such as black holes can heat surrounding gases to more than a million degrees. The high-energy X-ray radiation from this gas can be polarised – vibrating in a particular direction.The Imaging X-ray Polarimetry Explorer (IXPE) mission will fly three space telescopes with cameras capable of measuring the polarisation of these cosmic X-rays, allowing scientists to answer fundamental questions about these turbulent and extreme environments where gravitational, electric and magnetic fields are at their limits, the US space agency said.
“We cannot directly image what’s going on near objects like black holes and neutron stars, but studying the polarisation of X-rays emitted from their surrounding environments reveals the physics of these enigmatic objects,” said Paul Hertz from the Science Mission Directorate at NASA Headquarters in Washington. “IXPE will open a new window on the universe for astronomers to peer through. Today, we can only guess what we will find,” Hertz noted.
NASA’s Astrophysics Explorers Program requested proposals for new missions in September 2014. Fourteen proposals were submitted, and three mission concepts were selected for additional review by a panel of agency and external scientists. NASA determined the IXPE proposal provided the best science potential and most feasible development plan.Ball Aerospace in Broomfield, Colorado, will provide the spacecraft and mission integration. The Italian Space Agency will contribute the polarisation sensitive X-ray detectors, which were developed in Italy, NASA said.
