NASA’s Dawn spacecraft is set to reach in early June its new, final orbit which will be less than 50 kilometres above the surface of the inner solar system’s only dwarf planet — 10 times closer than the spacecraft has ever been.

Soon after, it will begin collecting images and other science data, and that very low orbit will also garner some of Dawn’s closest images yet, NASA said on Thursday.


The spacecraft will collect gamma ray and neutron spectra, which help scientists understand variations in the chemical makeup of Ceres’ uppermost layer.

“The team is eagerly awaiting the detailed composition and high-resolution imaging from the new, up-close examination,” said Dawn’s Principal Investigator Carol Raymond of NASA’s Jet Propulsion Laboratory, Pasadena, California.

“These new high-resolution data allow us to test theories formulated from the previous data sets and discover new features of this fascinating dwarf planet,” Raymond added.

Dawn was launched in 2007 and has been exploring the two largest bodies in the main asteroid belt, Vesta and Ceres, to uncover new insights into our solar system. It entered Ceres’ orbit in March 2015.

The transfer from Dawn’s previous orbit to its final one is not as simple as making a lane change.

Dawn’s operations team worked for months to plot the course for this second extended mission of the spacecraft, which is propelled by an ion engine.

Engineers mapped out more than 45,000 possible trajectories before devising a plan that will allow the best science observations, NASA said. (IANS)

Tech giant Amazon has expanded the sound detection capabilities of Alexa along with more features.

Tech giant Amazon has expanded the sound detection capabilities of Alexa along with more features. Alexa can now identify the sounds of running water and appliances beeping, reports Android Central. This means users can set up an Alexa routine to notify themselves when the washer beeps to indicate that laundry is finished, the report said.

When Alexa detects that the faucet has been left open, it will send users a notification as well so they can take appropriate action, it added. Amazon previously said at its event in September that it would add the ability to programme Alexa to recognise custom sounds, but that feature has yet to arrive. Having said that, the two new sound detection capabilities not only help users save energy, but they also make it easier to avoid paying for unnecessary charges on your home utilities, the report said.

The retail giant has also announced ultrasound motion detection, which will allow you to set up "Occupancy Routines" on additional Echo devices. This feature allows your smart speaker to detect nearby motion and initiate a routine, such as turning on the lights. It is compatible with many of the best Alexa speakers including the 4th-gen Echo, Echo Dot and Echo Dot with Clock. (IANS/ MBI)

For the study, the team involved a small yet significant number of participants who took a probiotic capsule twice a day for six days and then took two days off. They then repeated the cycle.

Probiotics may significantly improve the symptoms of pregnancy-related nausea, vomiting and constipation, finds a new study.

The study, published in the journal Nutrients, showed that nausea hours (the number of hours participants felt nauseous) were reduced by 16 per cent, and the number of times they vomited was reduced by 33 per cent.
