Isro’s PSLV C-44 successfully places military satellite Microsat-R in orbit

ISRO的PSLV C-44成功将军用卫星Microsat-R送入轨道

CHENNAI: The Indian Space Research Organisation (Isro) registered its first success of the year in a midnight journey of its Polar Satellite Launch Vehicle to space which injected a 740kg imaging satellite for military applications into orbit with precision before going to demonstrate a new technology that can eventually reduce space debris.

钦奈:印度空间研究组织(Isro)的极地卫星运载火箭于午夜时分发射进入太空，取得了今年的首次成功 ，该火箭将一颗用于军事用途的740公斤成像卫星精确送入轨道，随后将展示一项最终能够减少太空碎片的新技术。

PSLV C-44 lifted off with Microsat R, a military application satellite, and Kalamsat , a 10cm cubesat made by students, at 11.37pm on Thursday from the first launch pad at Satish Dhawan Space Centre in Sriharikota.

周四晚11点37分，PSLV C-44搭载军事应用卫星Microsat R和学生们制作的10厘米立方卫星Kalamsat，从斯里赫里戈达岛萨蒂什·达万航天中心的1号发射台升空。

The launch is PSLV’s 46th flight and the first flight with a new variant of PSLV called PSLV-DL with two strap-ons, each carrying 12.2-tonne of solid propellent.

此次发射是PSLV的第46次发射，也是PSLV系列的新型PSLV- dl卫星的首次发射，PSLV- dl有两个捆绑式助推器，每个可携带12.2吨固体推进剂。

Around 13 minutes into the mission, the fourth and final stage (PS4) of PSLV injected the primary payload Microsat-R at an altitude of about 277.2km. Microsat R has been developed by Defence Research and Development Organisation (DRDO) laboratories.

在执行任务大约13分钟后，PSLV的第四和最后一级(PS4)在大约277.2千米的高度将主要有效载Microsat-R送入轨道。Microsat-R由国防研究与发展组织(DRDO)实验室开发。

PM Modi tweeted a congratulation to the scientists behind the successful launch

Congratulating the team for the successful mission, Isro chairman K Sivan said this was the first that PSLV was “flown to the lowest orbit.”

Sivan congratulated the students who designed Kalamsat and said, “For the first time the PS4 will be revived for students to do experiments.”

莫迪总理在推特上向完成这次成功发射的科学家们表示祝贺。

ISRO主席K Sivan祝贺该小组圆满完成任务，并表示这是PSLV首次“飞到最低轨道”。Sivan向设计Kalamsat的学生们表示祝贺，他说:“PS4将首次被重新启用，以供学生们做实验。”

After the injection of Microsat-R, the PS4 would be reignited and shut off twice, as the stage with an increased velocity is raised to an orbit about 450km in altitude.

将Microsat-R卫星送入轨道后，PS4将被重新点燃并关闭两次，因为增速阶段被提升到450公里高的轨道上。

An hour and 40 minutes after the launch, the PS4, which would become a rocket debris after its engine is shut off and its fuel depleted, would be revived through solar panels and batteries. Kalamsat, weighing about 1.2kg, still secured to the stage, would be then activated.

发射一小时40分钟后，PS4将通过太阳能电池板和电池重新启动。在发动机关闭、燃料耗尽后，PS4将成为火箭碎片。Kalamsat卫星重约1.2公斤，仍被固定在这一级，然后将被激活。

PS4 is the smallest of the stages in size with a height of 2.5m and a diameter of 1.34m carrying 1.6 tonne propellent. With two liquid engines applying a thrust of 7.6kN each, PS4 is responsible for the correct injection of the payloads into their respective desired orbits.

PS4是尺寸最小的一级，高度2.5m，直径1.34m，运载1.6吨推进剂。两台液体发动机各施加7.6kN的推力，PS4负责将有效载荷精确射入各自的轨道。

According to Isro officials, PS4 will stay ‘alive’ for the next six months before it drifts away and disintegrates upon reaching the earth’s atmosphere. In the meantime, the cubesat made of space grade aluminium will be tested for its communication module, onboard computer, solar panels and electronics designed and developed by Indian students. The data from the tiny satellite will be collected by ground stations.

根据ISRO官员的说法，PS4将在接下来的六个月里“存活”，直到飘散并在到达地球大气层时解体。与此同时，由太空级铝制成的立方卫星将接受印度学生设计开发的通信模块、机载计算机、太阳能电池板和电子设备的测试。这颗微型卫星的数据将由地面站收集。

Great to hear about this success of India and ISRO. This military satellite is a fruit of many years of labour which started with IRS ( Indian Remote Senesing satellite series). This s hould give Indian intelligence a boost that is needed to get satellite surveillance info from across the globe. Modi ji has strengthened Indian intelliegence a lot and should countine do do so in uears to come.

很高兴听到ISRO成功发射的消息。这颗军用卫星是印度遥感卫星多年努力的成果，这有利于印度情报部门从全球各地获取卫星监控信息。莫迪极大地加强了印度情报机构的力量，再接再厉。
