The span after the first pregnancy is the most vulnerable period of a woman’s life as the body remains weak and ready to fertilize the egg. Hence, it is important to stay safe as the researchers believe that a woman must allow the body to prepare for one year before she accepts another pregnancy. This will not only reduce the health risk of the mother but also of the baby.
The researchers have conducted a study, which has cleared a lot of misconceptions and myths surrounding the family planning. The study was conducted by the Harvard TH Chan School of Public Health and the UBC or University of British Columbia on 150,000 births in Canada. It has revealed that the women don’t have to wait for 18 months to conceive the second issue, which is mentioned in the latest guidelines of the World Health Organization or WHO.
The researchers have cleared the doubt regarding the risks associated with the smaller gaps between the two pregnancies. They mentioned that the mortality rate of the infants and mothers increase at an exponential rate along with the premature births and smaller babies. Also, the chances become more prevalent for the older ladies.
According to Dr. Wendy Norman, the study author, this is great news for the women who are above 35 years as they don’t have to waste 18 months before conceiving another child. She also encouraged the mid-aged mothers by stating that if the women are willing to take another child, they can plan with a year gap in between. Not only the time reduces the risks of health but also depletes the complications of the delivery.
As per the current guidelines mentioned by the WHO, women must keep a gap of 18 to 24 months before planning a second child. However, the new study has nullified this claim and has suggested the people maintain a gap of 12-18 months between two pregnancies.
Four new proposed satellite constellations have been approved by US Federal Communications Commissions and it also authorized nearly 8000 small telecom satellites that will now serve US agencies from low earth orbits. The new regulation will now allow California based SpaceX and Ottawa based Telesat to expand their constellations that were approved last year and fill it with satellites in V-band spectrum. Kepler Communications and LeoSat based in Canada and Netherlands also got approvals, and while the former will use 140 Ku-band satellites the latter will apply 78 Ka-band satellites. Among all four firms that got approval Hawthorne based Space X has the largest constellation of 7518 satellites called VLEO that would operate just below 350 kms above earth.
SpaceX says that at this altitude the drag of atmospheric gravity would pull down spent satellites within a month putting to rest concerns about the amount of debris that these satellites would leave in spatial orbits. Three of the firms whose proposals have been approved have already placed their demonstration satellites in orbit. While SpaceX launched two prototype satellites in February, Telestat launched two prototypes in January. Telestat has given study contracts to Airbus Defense and Space team for evaluation about building its constellation.
Kepler has just one satellite prototype in orbit that was launched in January from Chinese Long March 11 and is planning to launch a second one in November through Indian PSLV while a third one is under construction. These prototypes will test communication ranges between earth and space for connectivity of Internet of Things and also connect other satellites in space through inter-satellite links. LeoSat had plans underway to launch two prototype satellites next year, but deferred them as a cost cutting move and instead will do ground tech validation with Thales Alenia Space and its investor Sky Perfect Jsat of Japan.
