SpaceX launched 60 mini satellites Monday, the second batch of an orbiting network meant to provide global internet coverage.
The Falcon rocket blasted into the morning sky, marking the unprecedented fourth flight of a booster for SpaceX. The compact flat-panel satellites – just 575 pounds (260 kilograms) each – will join 60 launched in May.
SpaceX founder and chief executive Elon Musk wants to put thousands of these Starlink satellites in orbit, to offer high-speed internet service everywhere. He plans to start service next year in the northern U.S. and Canada, with global coverage for populated areas after 24 launches.
Last month, Musk used an orbiting Starlink satellite to send a tweet: “Whoa, it worked!!”
Employees gathered at company bases on both coasts cheered when the first-stage booster landed on a floating platform in the Atlantic.
“These boosters are designed to be used 10 times. Let’s turn it around for a fifth, guys,” company’s launch commentator said.
This also marked the first time SpaceX used a previously flown nose cone. The California-based company reuses rocket parts to cut costs.
Stacked flat inside the top of the rocket, the newest satellites were going to maneuver even higher following liftoff, using krypton-powered thrusters. SpaceX said there was a potential problem with one of the 60 that could prevent it from moving beyond its initial 174 mile-high (280 kilometer-high) orbit. In that case, the faulty satellite will be commanded to re-enter and burn up harmlessly in the atmosphere.
Each satellite has an autonomous system for dodging space junk. In September, however, the European Space Agency had to move one of its satellites out of the way of a Starlink satellite. SpaceX later said it corrected the problem.
SpaceX is among several companies interested in providing broadband internet coverage worldwide, especially in areas where it costs too much or is unreliable. Others include OneWeb and Jeff Bezos’ Amazon.
According to Musk, Starlink revenue can help SpaceX develop rockets and spacecraft for traveling to Mars, his overriding ambition. (VOA)
It features three precise airflow speeds, to suit your styling and four precise heat settings, including constant cold shot. The cold shot immediately deactivates the heating element, for cooler air to set your style. The Coanda to curl barrels harness an aerodynamic phenomenon and the Coanda to smooth which uses Dyson brushes to attract hair to the surface of the brush, propelling air along the hair strands for a smooth, straighter style. It's powered by the Dyson digital motor V9, a 13-blade impeller spins at up to 110,000rpm, generating 3.2kPa. Powerful enough to produce the air pressure needed to create the Coanda effect. The intelligent heat control measures airflow temperature over 40 times a second, intelligently controlling the heating element to keep the temperature under a 150 degree Celsius. Preventing extreme heat damage. "Great styling and takes lesser effort than the usual blow drying. Saving lots of visits to the salon, absolutely love it!" says a salon regular who switched her weekly visits to the salon for the at home Dyson experience. (IANS/ MBI)
The discovery is significant because it's rare to find gas giants -- like Saturn in the solar system -- as close to their host star as they were in this case. The researchers cannot yet explain why it occurred there, but it makes the finding especially useful because it could help scientists form a more accurate understanding of the parameters for how planets and planetary systems develop.
The term "exoplanets" is used to describe planets outside of the solar system. The number of exoplanets that have been identified by astronomers numbers fewer than 5,000 in all, so the identification of hundreds of new ones is a significant advance. Kepler's original mission came to an unexpected end in 2013 when a mechanical failure left the spacecraft unable to precisely point at the patch of sky it had been observing for years.
But astronomers repurposed the telescope for a new mission known as K2, whose objective is to identify exoplanets near distant stars. Data from K2 is helping scientists understand how stars' location in the galaxy influences what kind of planets are able to form around them. (IANS/ MBI)

Apply moisturizer: The baby's skin is very sensitive and the harsh, dry, and cold air can make the skin dry. Therefore, apply a good moisturizer to keep it soft and smooth. Choose a moisturizer made of milk cream and butter, especially for children. This will keep the skin of your baby soft.
Dress your baby comfortably: Choose comfortable dressing for your baby. Avoid wrapping your baby in thick sweaters, gloves, and socks. This will restrict its movement and he/she will become irritable. Choose clothes depending on the room temperature. The clothes should cover his/her baby but should not restrict movement. You can use light gloves and socks to cover your hands and feet to keep your baby warm at night.
Breastfeeding: Breastfeeding is the most important activity that can keep your baby healthy. Breast milk consists of required nutrients and antibodies that will enhance the immune system of your baby and will protect him/her against diseases. During breastfeeding your baby will feel warm and cosy that will also give him comfort.
Take care outdoors: If you want to take your child outdoors make sure it is not freezing temperature. Take your child out for fresh air only if the temperature is not too cold and remember to cover your baby properly before taking them out. Taking your baby out will help to give fresh air and will improve their health.
Common issues that may arise in newborn babies during winters:
- Skin allergies
- Digestive issues
Parents can take care of their newborn babies from various diseases that may affect them in the winters in the following ways:
* If your baby suffers during the winter season, you should consult a pediatrician.
* Keep your baby well hydrated. Keep breastfeeding your baby and also give water if necessary.
* Cuddle your baby lovingly and give him warmth along with other precautions.
How often to give a bath to your baby in winter?
It is not necessary to give a bath to your baby every day. You can bathe your baby after 2-3 days in winter. You can sponge bathe your newborn every other day in winter. Check the temperature of the room before giving a bath to your baby. The room temperature should be warm and comfortable for your baby. Check the temperature of the water. Make sure the water is not too hot or cold. The temperature of the water should be right for the body of your baby. Check the temperature by touching the water with your elbow or wrist. Use mild soap and shampoo to bathe your baby in winter. Also, apply oil and moisturizer to the skin to keep it soft and prevent skin allergies. (IANS/ MBI)
